nginx (pronounced as engine-x) is a lightweight, high performance http server, reverse proxy server, IMAP, SMTP and POP3 server. In this tutorial my test box hostname and ip address are “server.unixmen.com” and “192.168.1.200”.
Install EPEL Repository
nginx will not be found in Official CentOS repository, so lets install EPEL repository first.
[[email protected] ~]# wget http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm [[email protected] ~]# rpm -ivh epel-release-6-8.noarch.rpm
Install MySQL
[[email protected] ~]# yum install mysql mysql-server -y
Start the MySQL service and make to start automatically on every reboot.
[[email protected] ~]# /etc/init.d/mysqld start [[email protected] ~]# chkconfig mysqld on
Set MySQL root password.
[[email protected] ~]# /usr/bin/mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL      SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current password for the root user. If you've just installed MySQL, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): ## Press Enter ## OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. Set root password? [Y/n]    ## Press Enter ## New password:               ## Enter new password ## Re-enter new password:      ## Re-enter new password ## Password updated successfully! Reloading privilege tables.. ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n]    ## Press Enter ## ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n]   ## Press Enter ## ... Success! By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n]   ## Press Enter ## - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n]   ## Press Enter ## ... Success! Cleaning up... All done! If you've completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL!
Install nginx
[[email protected] ~]# yum install nginx -y
Start nginx and make it to start automatically on every reboot.
[[email protected] ~]# /etc/init.d/nginx start Starting nginx: [ OK ] [[email protected] ~]# chkconfig nginx on
Stop Apache or any other web servers if you have.
[[email protected] ~]# /etc/init.d/httpd stop [[email protected] ~]# chkconfig httpd off
Open the nginx port in your firewall/router if you want to access the web server from other systems.
[[email protected] ~]# vi /etc/sysconfig/iptables -A INPUT -p udp -m state --state NEW --dport 80 -j ACCEPT -A INPUT -p tcp -m state --state NEW --dport 80 -j ACCEPT
Restart iptables
[[email protected] ~]# /etc/init.d/iptables restart
Now point your web browser with “http://192.168.1.200”. The test page of nginx will open.
Install PHP
[[email protected] ~]# yum install php php-common php-fpm -y
Start php-fpm service.
[[email protected] ~]# /etc/init.d/php-fpm start [[email protected] ~]# chkconfig php-fpm on
Test PHP
Create a sample “testphp.php” file in nginx document root folder and append the lines as shown below.
[[email protected] ~]# vi /usr/share/nginx/html/testphp.php <?php phpinfo(); ?>
Now open the testphp.php file in browser using http://192.168.1.200/testphp.php. It will display the details about php package.
Configure nginx
Open nginx config file and set the worker_processes (i.e No of CPU’s in your system). To see the no of cpu, use the command “lscpu”. In my case its “1”. So i set this as ‘1’.
[[email protected] ~]# vi /etc/nginx/nginx.conf worker_processes 1;
Save and close the file and Edit the “/etc/nginx/conf.d/default.conf” as shown below.
[[email protected] ~]# vi /etc/nginx/conf.d/default.conf server { listen 192.168.1.200:80; server_name server.unixmen.com
Save and close the file. Restart nginx service now.
[[email protected] ~]# /etc/init.d/nginx restart
Thats it your nginx web server is ready to use.
